From what I have heard, stories usually change quite a bit during the development process so I'm not sure it's wise to plot out minute details before a game goes into serious production. The reason for that is that ultimately the story has to get "bent" as needed to support interesting gameplay.
As far as whether the stories are worthy successors to KF, so much depends on how it is fleshed out in the final game.
The outline for 4 sounds intriguing, but I don't think the name Solomon is ideal. It brings to mind pictures of an old, bearded man or maybe a fat, short, Jewish jeweler wearing a loop and a yarmulke. I think a fantasy name that only hints at an English word is better. Actually, just plain "Solo" seems like a nice name.
In 5, swimming between islands seems like a neat gaming convention to explore. I'm not crazy about the main character being a royal. I think playing an "underdog" is always more interesting. Like in ICO where you start as a discarded cursed child who struggles to find his path. If he had started as a prince with a royal guard retinue, it would have changed the game's feel considerably.
In 6, the "ability to venture far and wide across time and space" seems too abstract and powerful. Again, a flawed and weak character who struggles against all odds seems more interesting than a time traveling teleporter. Having an animal companion is nice.
If you're intrigued with exploring a fully fleshed out story, maybe writing novels would be a good way to go? It might also be hard to find other game developers to jump onboard with your story visions. I once saw a post on a game-maker's forum where a person was suggesting a plotline for the developer's next game. The developer replied "stories are like nostrils, everyone has at least two and no one wants to pick someone else's".
